NEW BRUNSWICK — A man who died in a house fire Saturday has been identified as 74-year-old Robert Whitehead.

Firefighters carried Whitehead from the fire at 168 Commercial Ave. and brought him to Robert Wood Johnson University Hospital, where he was pronounced dead, police Lt. J.T. Miller said.

He said investigators have yet to determine the cause of the fire, but it does not appear to be suspicious or to have been intentionally set.

The blaze was reported about 6 a.m. Saturday, but it took firefighters more than three hours to bring the two-alarm blaze under control because home was cluttered with items, with passageways only two feet wide, officials said.

The fire started in the basement and caused the first floor to collapse, fire officials said. Neighbors said Whitehead was known for collecting items and not throwing anything away.
